Highlights

  • Your super’s investment mix changes automatically as you age.
  • Younger members hold more growth assets like shares for higher returns.
  • As retirement nears, your super shifts toward safer assets like bonds and cash.
  • This reduces risk over time without requiring you to make changes.
  • Lifecycle strategies are built into most MySuper default funds.

When it comes to building wealth for retirement, your superannuation, commonly referred to as super is one of the most powerful tools available. But how your super grows over time depends not only on your contributions and the length of time you invest, but also on your investment mix: the proportion of assets like equities (shares), bonds (fixed interest), property, and cash held within your super fund.

Getting the right mix is critical for balancing long-term growth with stability. Understanding how each asset class works and how they behave in different market conditions can help you make more informed decisions about your super investment strategy.

Understanding the Main Asset Classes

  • Equities (Shares)

Equities represent ownership in companies and typically offer higher long-term returns compared to other asset classes. However, they also come with higher short-term volatility. Australian and international shares are commonly held in super portfolios to drive capital growth. According to the Australian Securities and Investments Commission (ASIC), shares are ideal for investors with a long-time frame who can tolerate market ups and downs.

  • Bonds (Fixed Interest)

Bonds are loans made by governments or corporations, offering regular interest payments and typically less risk than shares. They can serve as a cushion during the market downturn, helping to stabilise your portfolio. Bonds may be issued in Australia or overseas, and their value can fluctuate based on interest rates. The Reserve Bank of Australia (RBA) notes that fixed income investments tend to perform well when interest rates fall, although they offer lower returns over the long term.

  • Cash

Cash investments like term deposits or savings accounts provide stability and liquidity but offer minimal growth potential. They are suitable for short-term goals or for older investors seeking to preserve capital. The Australian Taxation Office (ATO) highlights that cash is the least risky asset class but is unlikely to keep pace with inflation over time.

  • Property and Alternatives

Many super funds also invest in property (both listed and unlisted) and alternative assets such as infrastructure, private equity, or commodities. These offer diversification benefits and can perform well when traditional markets struggle. The Australian Prudential Regulation Authority (APRA) reports that large MySuper funds often hold a diversified mix, including a growing portion in alternatives to reduce risk concentration.

Why Asset Allocation Matters

Asset allocation refers to how your money is divided among different classes of asset. It’s a critical determinant of your portfolio’s long-term returns and risk exposure. For example:

Lifecycle and Default Options

If you haven’t selected an investment option, your super is likely in a MySuper default fund. These often use a "lifecycle" strategy—investing in growth assets when you're younger and gradually shifting to more defensive assets as you approach retirement. This helps align risk with your age and stage of life. The Australian Government's MoneySmart service explains that lifecycle options are designed to manage risk without requiring members to make ongoing decisions.

Reviewing Your Super Mix

Markets change, and so do your financial goals. That’s why it's important to review your super investment mix regularly, especially during major life events like a new job, marriage, or nearing retirement. Use the online tools and product dashboards provided by your super fund and compare key metrics like long-term performance, fees, and asset allocation.

The right asset mix can make a meaningful difference in how your super grows over time. While equities offer long-term growth, bonds and other assets play a vital role in cushioning risks. Understanding the trade-offs between risk and return—and aligning them with your personal goals—can help ensure your super works as hard as you do.
